Toronto to develop RNG facility in partnership with Enbridge

The city of Toronto has announced plans to produce renewable natural gas (RNG) at its Dufferin Solid Waste Management Facility. The project will be developed in partnership with Enbridge Gas Distribution Inc.

According to information released by the city of Toronto, new equipment will be installed at the Dufferin site later this year that will convert raw biogas produced from processing the city’s organic waste into RNG. The resulting RNG will then be injected into the natural gas grid, allowing the city to use RNG to fuel its waste collection trucks.

The city said it has partnered with Enbridge to design and construct the new equioment, as well as its operation and maintenance for the first 15 years.

The new equipment is expected to begin operations during the third quarter of 2019. Enbridge and the city of Toronto estimate the Dufferin RNG facility will produce approximately 5.3 million cubic meters of RNG annually, enough to fuel 132 garbage trucks.

 “The Dufferin Organics Processing Facility is one of two state-of-the-art City facilities that use innovative pre-processing and anaerobic digestion technology to break down organic material,” said Councillor Jaye Robinson (Ward 25 Don Valley West), chair of the city's Public Works and Infrastructure Committee. “Introducing RNG production at the site further emphasizes its status as a leading sustainable solid waste management facility.”

“This project represents a path to low-carbon fuel for the city and will play an important role in helping us reach our goal of reducing greenhouse gas emissions by 80 percent by 2050,” said Toronto Mayor John Tory. “I'm committed to working with city council and city staff to ensure we are meeting our climate change action goals and to creating a more sustainable Toronto.”

"We all agree that we must have cleaner or lower carbon energy options to heat our homes and move our vehicles,” said Cynthia Hansen, executive vice president, utilities and power operations, Enbridge Inc. “While traditional natural gas is the cleanest-burning conventional fuel, RNG is the first step in 'greening' the natural gas system. I commend Mayor Tory and the city of Toronto for their vision and commitment and we look forward to additional opportunities to partner with and support the city."

The Dufferin RNG project is the first of four waste-to-RNG production opportunities identified by the city of Toronto. Once all four RNG sites are up and running, the city estimates it will be able to produce approximately 65 million cubic meters of RNG annually.
